ISIN: ZM0000000037 A Quiet Giant: The Origins and Heritage of ZCCM ZCCM Investments Holdings PLC (ZCCM-IH) is one of Zambia’s most significant and historically influential companies — a remnant and evolution of the nation’s mining legacy. Its roots trace back to the Zambia Consolidated Copper Mines (ZCCM) , which emerged after the nationalization of the mining sector in the early 1970s, when Zambia took ownership of the assets previously operated by private mining companies.
